Program that counts from 100 to 0.

So, today uploading a script of program that i maked by 3 minutes. The sense of program(how you can call it, "test") is to count to 0 and close the program. Here the script go:

local count = 100
while true do
term.clear()
term.setCursorPos(1,1)
print(count)
count = count-1
sleep(0.5)
if count <= 1 then
break
end
end

Maybe will help. Also the part of script can be used in API. :D

Moved to Programs.

I can't see any use from a countdown timer, but it's a start!

But hey-ho

countDown = function(start)
   for a = start, 1, -1 do
      term.setCursorPos(1,1)
      term.write(a.." ")
      sleep(0.5)
    end
end

One things that's useful to note is that for loops can have steps, in the format:

for variable = start,stop,step do

Step defaults to 1, but counting down can be done by having the step be -1. It took me a while to realize that myself.
